如何在ListView中获取水平滚动条的高度

Question

Can anyone tell me how can I get the height of horizontal scrollbar in ListView in C#? is it the same as the standard Horizontal scrollbar, if so is there any windows function that return that? basically I'm using ListView with OwnerDraw and want to know exactly how big is my client area which excludes ColumnHeader area and HorizontalScrollbar area.

Thanks

Answer 1

SystemInformation.HorizontalScrollBarHeight

Answer 2

Control.ClientRectangle excludes scrollbars and borders.

    listView1.Scrollable = true;
    Console.WriteLine(listView1.ClientRectangle);
    Console.WriteLine(listView1.Size);
    listView1.Scrollable = false;

    Console.WriteLine(listView1.ClientRectangle);
    Console.WriteLine(listView1.Size);

On .Net CF, where SystemInformation.HorizontalScrollBarHeight and SystemInformation.VerticalScrollBarWidth don't exist, some P/Invoke is required:

public sealed class Native
{
    public static Int32 GetVerticalScrollbarWidth()
    {
        return GetSystemMetrics(SM_CXVSCROLL);
    }

    public Int32 GetHorizontalScrollbarHeight()
    {
        return GetSystemMetrics(SM_CYHSCROLL);
    }

    [DllImport("coredll.dll", SetLastError = true)]
    public static extern Int32 GetSystemMetrics(Int32 index);

    public const Int32
        SM_CXVSCROLL = 2,
        SM_CYHSCROLL = 3;
}
